GIL-CUP.

SPECIFICATION forming part of Letters Patent No. 567,182, datedSeptember 8, 1896.

Application filed November 19, 1895. Serial No. 569,396. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM H. WILKIN- SON, a citizen of the UnitedStates, residing at Medway, in the county of Norfolk and State ofMassachusetts, have invented certain new and useful Improvements inOil-Cups; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will en able others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to figures of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in oil-cups, particularly thatclass in which a lever is employed to lift the valve from its seat, andwhereby the device adapted to regulate the feed-supply is then held fastby said lever in order to prevent subsequent disturbance of the feed,either to increase or dimin-' ish it.

My invention is embodied in the arrange ment by which the lever isequipped with a spur, pin, or other equivalent, in order that saidelement may positively engage with the feed-regulating device when thelever is in such position as to open the valve. Hence no change in thefeed can occur from vibrations or jars incidental to the movingmechanism to which the oil-cup may be attached.

The drawings represent, in Figure 1, a vertical sectional elevation ofan oil-cup embodying my invention, the lever being up and the valveopen. Fig. 2 is a cross-section on line 1 1, enlarged. Fig. 3 is avertical section of a modification. Fig. 4 is a plan, and Fig. 5 is atransverse section on line 4 4, of a round-headed screw which serves toregulate the feed, as in Fig. 3. Fig. 6 is a sectional viewlongitudinally of the lever on the plane indicated in Fig. 7, showing amodified construction. Fig. 7 is a plan of the same.

This invention, as before premised, concerns that class of oil-cupswhich are opened and closed by a rocking lever, and relates particularlyto an invention embodied in United States Letters Patent No. 542,854,issued July 16, 1895. In the drawings herewith presented, 2 representsan oil cup consisting of a reservoir 3, centrally of which is imposed aspring-actuated valve 4, operated by a lever 5, secured to theprojecting end of the valve-spindle 6. The upper portion of said spindleis formed with a longitudinal slot 7, while a feed-regulating device inthe shape of a screw 8 engages the extremity of the spindle and may haveendwise movement therein, while the lower end of said screw extends intothe slot.

The operating-lever by which the oil-cup valve is controlled consists ofa lever bifurcated at 9 9, while a bolt 10, which passes transverselyacross and through the slot, serves to secure the said lever to theoil-cup.

From the above description of parts it will be seen that when the leveris tilted from a horizontal position into an upright one, the foot ofthe lever acting as a fixed point or fulcrum, the bolt 10 is thrustagainst the end of the feed-screw, and the position of said screwaccordingly determines the distance the valve is raised from its seatand thereby regulates the quantity of lubricant to be delivered.

The purpose of my invention is to enable the feed to be regulated moreclosely than when the sides of the lever are contiguous with thepolygonal head of the feed-screw and to permit a round-headed screw tobe employed if occasion requires.

Under my invention it will be seen that the sides of the bifurcatedlever do not contact with the head of the regulating-screw. Hence 'tocause the lever to hold the screw from movement,which otherwise mightoccur when the valve is open, I have provided the lever with a spur orpin 12, which enters the head of the screw.

It will be understood that changes in the adjustment of the screw willnot affect the interlocking of the screw-head with the spur, since for agiven length of screw the bolt 10 will always contact against the end ofsaid screw. Hence the head of the screw will remain undisturbed withrelation to the spur, the effect of moving the screw being merely toincrease or diminish the movement of the valve.

To permit the lever to engage the screw while the latter is in anyposition, numerous peripheral holes 13 are created, as shown in Figsrland 2. In this construction the spur is preferably attached to a plate14 transversely at the upper end of the lever. Hence the lever can beswung up or downonly from the open side, since the pin striking againstthe screw prevents movement in the opposite direction.

In Figs. 3, 4, and 5 is shown a modified form of a screw-head, in whichradial notches or grooves are out upon the top of the head and thefastening-stud 12 is eccentrically disposed, and consequently, when thelever is thrown into an upright position, in order to open the valve,moves in across the head, as indicated at 12? in Fig. 4, engaging one ofthe numerous grooves in said head. This engagement effectually preventsany rotation of the adjusting-screw, and the desired feed remainsconstant untilthe lever is" thrown. down, when adjustment may be eflfected.

When it is desired tochange the feed, and thereby increase or diminishthe flow, the lever has usually been thrown down. This act necessarilyshuts the valve and stops the sup ply of lubricant. To obviate thisdifficulty I create an opening 16 longitudinally through the head oftheleve'r for the introduction of a screw-driver; but under theconstruction as shown in Fig. 1 it becomes necessary to incline thelever slightly to disengage the holding device from the screw-head. Topermit this, and yet to allow the screw-driver to properly engagethehead of the screw, this opening is made flaring from the bottomupwardly.Thus it will be seen that without stopping the flow of lubricant thequantity can be changed as conditions demand. However, I do not wishtob'e limited to the locking of the feedscrew by means of the lever,since I consider my invention is embodied in the form of the lever andits relation to the feed-screw, where- 1 by the latter may be adjustedwithout stop-- I ping the flow of lubricant and without change in theposition of the lever. 5

What I claim is- 1. In combination with a fluid-reservoir, a valvehaving a spindle slotted at one end, a rocking valve-lever secured tothe spindle by a bolt movable in the spindle-slot, a regulatingfeed-screw having a circular head, and a device carried by the lever tointerlock with the feed-screw when the valve is open, substantially asdescribed.

2. A valve-operating device comprising a valve having a valve-spindleslotted at one end, a valve-lever secured to said spindle by a boltmovable in said slot, a regulating-screw having around head and movableendwise in the spindle, and a locking device carried by ,the lever toengage thescrew head substam i tially as stated.

3. Ina valve-operating device a valve, a islotted valve-spindle, aswinging lever to {straddle the spindle, and a bolt movable in ;the slotand which secures the lever to the spindle, combined with an adjustablefeedscrew havinga cylindrical head and movable endwise in the spindle, aseries of depressions in the screw-head, and a stud carried by the Qlever to engage the depressions when the valve is open, substantially asset forth. 1 4. In combination with a fluid-reservoir,a ivalve having aspindle slotted at one end, a rocking valve-lever secured to the spindleby 5 a bolt movable inthe spindle-slot, a regulating feed-screw having aserrated head and an opening longitudinally inthe head of the le- @whenthe valve is. open, substantially as explained.

In testimony whereof I affix my signature in presence of two witnesses.
